Torso Electronics Launches OS 2.0: A Massive Firmware Update for the S-4 Sculpting Sampler
Torso Electronics has just released OS 2.0, the most significant firmware update yet for their innovative S-4 sculpting sampler. This milestone upgrade represents a full realization of the S-4's original vision, delivering powerful new features, an overhauled workflow, and a complete rewrite of the core engine.
With OS 2.0, the S-4 transforms into an even more expressive and flexible instrument — built for creative control, dynamic performance, and fluid composition.
What’s New in S-4 OS 2.0
This update isn't just an improvement — it's a reinvention. Here are the major new additions:
🎛️ Perform: Global Macro Controls
The new Perform mode introduces global macro functionality. Users can map any parameter to eight performance knobs and four punch-in effect buttons, allowing dramatic, instrument-wide transformations with a single gesture.
🎚️ Scene: Instant Snapshot Recall
Scene lets you save and trigger full snapshots of parameters, machine states, and sample setups. With up to 128 scenes per project, you can build variations, switch samples, or recall entire setups instantly — all controllable via the device or MIDI Program Change.
⏱️ Temp: Temporary State Control
Engage Temp to temporarily tweak any parameter. When Temp is released, the S-4 instantly returns to its previous state — perfect for spontaneous flourishes during performance.
📁 Disc: Long-Form Audio Playback
The brand-new Disc device allows streaming directly from internal storage, making it possible to play unlimited-length samples. Whether you’re working with full-length stems, ambient field recordings, or extended loops, Disc opens the door to expansive audio possibilities.
📊 Follow: Dynamic Modulation via Envelope Following
Follow is a modulation device that uses the amplitude of audio signals — from track outputs or external inputs — to modulate parameters in real-time. This means live, reactive modulation that responds dynamically to your mix or external input.
Enhanced Workflow and Usability
OS 2.0 also brings a host of improvements that refine the S-4 experience:
-
Varispeed Recording in the upgraded Tape device enhances live looping capabilities.
-
New options for copying and duplicating devices, tracks, and scenes streamline creative workflow.
-
A fully refreshed interface improves navigation and clarity.
-
Numerous existing devices have been upgraded with additional functionality and deeper control.
Available Now – Free for All S-4 Owners

Whether you're a long-time user or just getting started, OS 2.0 makes the S-4 a more powerful, playable, and performance-ready sampler than ever before.
